Russian hamsters (primarily referring to Campbell’s dwarf hamsters and Roborovski hamsters) have lifespans that vary by breed and living conditions. Here are the details:
I. Basic Lifespan Range
Campbell’s Dwarf Hamsters
Their average lifespan is 1.5–2 years, though some individuals can live up to 2.5 years under ideal conditions.
Roborovski Hamsters
They have a relatively longer lifespan, typically 2–3 years, with rare cases reaching 3.5–4 years. They are the longest-lived among dwarf hamster breeds.
II. Key Influencing Factors
Housing Environment
Housing them alone reduces stress from fighting, which can extend their lifespan.
Keep temperatures stable between 18–24°C (64–75°F) and avoid extreme heat or cold.
Diet Management
Avoid high-sugar foods (such as fruits) to prevent diabetes.
A balanced diet is recommended, including specialized hamster food, fresh vegetables, and insect protein (e.g., mealworms).
Health Care
Elderly hamsters (over 1.5 years old) need regular checks for tumors and dental issues.
Diseases like wet tail require prompt antibiotic treatment.
III. Comparison with Other Breeds
Syrian Hamsters (Golden Hamsters): Lifespan of 2–3 years, slightly longer than most Russian dwarf hamsters.
Black-Bellied Hamsters: Wild individuals can live up to 8 years, but this has not been recorded in domesticated breeds.
Note: Inbreeding significantly shortens lifespans. It’s advisable to choose individuals from healthy, non-inbred lineages.
